My 20 amp circuit breaker keeps tripping. I have disconected all recepticals on the circuit and it still trips. Circuit 4 for my coach. Anyone experienced this? Any Suggestions?

Could be something that is hard wired, or a loose wire shorting.

Get digital ohmmeter and measure resistance between blades, check all and note the lowest resistance, then remove that outlet and inspect.

Is this just a plain outlet or is it a GFCI outlet? Have you had your motorhome plugged into it all along and this just started to happen? Does it trip as soon as you plug the rv in?

this just started to happen. I replace breaker and GFI. All Plugs in this circuit are not working. I reset and the breaker immediately trips. It trips the moment we have 110 power. (generator or land)

I am having a bit of trouble understanding what you are asking here, is this a problem with a outlet on your home that you plug your RV into? If this is on and in your house wiring that this is happening on, you have a dead short somewhere in that circuit. What is confusing me is your last statement. generator or land ? I don't understand this.

sorry. The breaker is in my coach. it tripps the moment we plug in or run the generator.

What does it say that 20 amp. breaker is for on the door of the panel? If you know this your problem is plugged into that circuit somewhere that has a dead short in it.

Dont forget to check outside receptacles , if they are on that circuit.

I am not sure what lights that this would be, all the lighting in your Coach had ought to be 12 vdc not ac. I am stumped trying to think of any lights that run on 120vac that would cause you this problem. Can you look around and see if you notice anything that is not working to try and narrow this down?

I have not tried outside receptcals. Thats a good Idea. I also can not figure out why it is labeled light. All lights work other than map light over driver seat.

Even that map light is 12 vdc, un plug everything from all the outlets inside and in the basement and then see if you can reset it, then start to plug things back in inside and see if you can see what is tripping it.

OK. checked outside recepticles. I have nothing plugged in to any of them outside or inside and the breaker still tripps.

You said you replaced the GFI receptacle. The GFI is usually the first one in a circuit. Disconnect that receptacle and see if it still trips the breaker. If not hook the receptacle back up but don't hook anything going out of it, just the input. Try again. If the breaker trips you will know it's the GFI receptacle.

The next step which should never be done unless you are an EE like me is what we call the SMOKE TEST. This test is preformed by putting in a 100 amp breaker in place of the 20 amp. Crank up the gen set and watch for smoke. Usually once the smoke is let out and you replace the area that let the smoke out with fresh smoke you should be good to go
